Application filed liay 21,

'To all whom t may concern Be it known that we, Joran llcnnrenri andEDWARD N. VVALsH, citizens olf the United States, residing at Joliet, inthe county ot lllill and State of llinois, have invented certain new anduseful improvements in Railway-Car Construc ns, of which the followingis a specification,

Our invention relates to railway cars of the type known as hopper cars,and has l'or its object to provide an improved car construction of thistype in which suitable pro vision is made for the proper distribution ofthe stresses imposed upon the car incident to its service.

With this object in mind we have illustrated in the accompanyingdrawings one embodiment of our invent-ion. ln these drawings- Figure lis a side elevation.

Figure 2 is a top plan view, and

Figure 3 is a cross section on the line 3X 3X of Figure l or' a sidedumping hopper car.

Hopper cars as commonly constructed embody a center sill extendingthroughout the car, and cross sills between the holsters toget-her withthe load enclosing members. ln carrying out our invention we dispensewith the usual center sill using in place thereof short center sill ordra-ft members l eX- tending from end sills 3a to a point just beyondthe inner ends of the truclrs. r1Fliese center sill sections we connectthrough an improved construction, with an ffl-shaped floor 7 having itsmembers 7 diverging downwardly and outwardly :trom its central andlongitudinally disposed apen 7b, thus lying over the inner ends of thecenter sill members and extending from one to the other of the bodybolsters, indicated at 2. Strut members 8 are disposed at suitableintervals between the licor members 7a below the line of the center sillmembers. The load enclosing` members ot the car in addition to theseVfloor members, comprise vertical end portions 3, the side walls 4l andthe inclined end portions 5 which latter slope downwardly and inwardlyfrom the vertical end portions 8 to a point 3 beyond the inner ends ofthe trucks. Extending across the ends oli the Qi-shaped flooringsections are flanged members 3b suitably connected to the A-shapedflooring members. Extending across these licor members at the innerSpeciieaton of Letters Patent.

end of each center sill member, said flanged member 3C and a cover plate3d rests upon ai d is secured to the members 3b and 3 at its iront andrear margins, while its lateral dimension is su'liicient to bridge thespace between and have its lateral margins secured to the under sides ofthe floor members 7: rlie inner end of the center sill member is securedin any suitable way to the support formed by the members 3b, 8C, 3d andsaid center sill member is further secured to the floor members throughthe medium of the liano'ed member 3e extending across the end or andsecured to the it-shaped floor and above the center sill to which it isalso secured. lt will thus be seen that the plate 3d lies in asubstantially horizontal position and extends longitudinally of and issecured to one horizontal lace of the draft sill while the flangedmember 3c extends transversely of and is secured to the oppositehorizontal lace of the draft sill. rlhus there is established a rigiddraft connection between the center sill section and the .l-shaped doorsection which will efficiently transmit the bufling and pulling loadsand it will be noted that the stresses are largely imposed edgewise uponthe cover plate 3d and by said plate distributed to the ffl-shaped floorsection from the four marginal inembers of the plate.

Between the trucks outwardly swinging doors 9, pii'oted at their upperedges below the sides 4, permit the discharge olf the lading ili'rointhe downwardly and outwardly sloping door members 7a. lt is customary incars otl this type, which are provided with high vertical sides, to tiethe sides together .,t the tcp by horizontal cross rods, in order 'oprevent the outward bulging of the sides, duc to the pressure of theload. lt is also customary to provide such cars with stakes attached tothe sides and to the cross beams oi the underframe. But according to thepresent invention, in order tc provide a rigid attachment of the sidesto the floor ci' the car and to prevent the outward bulging of the sidesusually compensated ior by the aroresaid cross rods at the top, we haveprovided gusset plate members l0 which extend downwardly and inwardlyfrom points near the top or' the sides to points well above the middleand suiiciently near the apex of the slo floor members 7a to rigidlystay the upper margins of the side walls. For cono ii,

venience of fabrication these members l may be made in sections l()21and 10" rigidly secured together as indicated at 10 and secured to thefloor members 7 byrflanged members 10d. These members 10 as shown extendinwardly from the sides for a considerable distance along the iioor andthus act to tie the upper portions of the sides to the inner portion ofthe floor and perform the functions not only of the horizontal crossrods above described but also of the usual side stakes. The outwardstrains at the top of the sides, therefore, due to the load, areresisted by the members l() and transmitted to the inclined floor. Thesemembers at the same time form a support for the sides of the car.

The inclined iioor members are supported on the center sill members atthe ends of the flooring through the medium of members 1Q, which arebent to conform to the shape of the apex of the floor and which areconnected to the center sill members by angle irons ll.

It will be seen that in our improved construction we have not onlyprovided a car in which the usual center sills and the usual cross beamsare dispensed with, and replaced by an ,ft-shaped floor member extendingbetween short center sill sections, but we have provided novelconstructions Awhereby stub sills at the ends of the car are connectedto this A-shaped floor member rigidly and in a manner that efficientlydistributes to said floor member the stresses imposed upon the car whenin service.
